As promised, developer Firaxis Games has released a massive new patch for 2010's turn-based strategy game Civilization V. The patch is now available for automatic download via Steam and the huge patch list is available to check out on the Steam web site.

There's lots of changes and improvements to many of the game's AI features in this new patch along with lots of gameplay changes as well (for example, the game's Stealth Bombers can now get promotions). There's also a boatload of change to the game's user interface and there's also been some bug fixes for mod support, achievements and more.

Would you like a game that looks like a Sim City title but lets players blow stuff up like a Command and Conquer game? Then Detour may be the game you have been waiting for. Indie developer Sandswept Studios announced today that its first game will be released for the PC via Steam on May 17.

The game uses a grid system much like Sim City where you can build structures and roads but you are not a govial mayor in this game; your goal is to also build units to blow up your enemies. The game will have a number of single player challenges, multiplayer and co-op modes for up to four players and a map editor so you can make your own levels and share them with others. Pricing for the game has yet to be revealed.

Two of the team members in charge of making the free first person shooter Nexuiz are close to releasing their first commercial game. Lee Vermeulen and Jesse McGibney of Alientrap have announced that Capsized, their sci-fi theme 2D platformer action game, will be released on Steam this Friday.

In addition to the full game, a demo of Capsized will be released on the same day, allowing folks to try out the gameplay features of the platformer, which has a space traveller exploring a planet he (or she?) has crashed on. The game also features local deathmatch and co-op modes, among others. The full verison of Capsized will be released for $9.99.

It's not exactly a shock but Valve's puzzle-shooter sequel Portal 2 finds itself on top of Steam's top 10 best selling PC games list for the past week. A bundle containing both Portal 1 and 2 was in second place this week and the original Portal game reentered the top 10 list in the number eight position.
